Description

Technical Field

[0001] This utility model relates to the technical field of packaging boxes, specifically to a packaging box printing device. Background Technology

[0002] Packaging boxes, as the name suggests, are boxes used to package products. They can be classified by material, such as cardboard boxes, tin boxes, wooden boxes, cloth boxes, leather boxes, acrylic boxes, and corrugated boxes, or by product name, such as mooncake boxes, tea boxes, goji berry boxes, candy boxes, exquisite gift boxes, local specialty product boxes, wine boxes, chocolate boxes, food, medicine, and health product boxes, food packaging boxes, tea packaging boxes, stationery boxes, etc. The functions of packaging boxes include ensuring product safety during transportation and enhancing the product's perceived quality.

[0003] The packaging box printing device with a correction mechanism disclosed in publication number "CN220841864U" includes a work frame with a conveyor belt inside for transport. A first support frame is fixedly installed on one side of the top surface of the work frame, and a first electric push rod is fixedly installed on the bottom surface of the first support frame. In actual operation, the packaging box printing device with a correction mechanism of this utility model allows the conveyor belt to transport the packaging box to the area below the printing component. The first electric push rod pushes the printing component down to print on the packaging box. A hot air blower heats the air, which is then sprayed onto the packaging box through a nozzle. A second electric push rod pushes a cleaning block to move up and down, bringing the brush plate into contact with the packaging box. A motor drives a first threaded rod to rotate, causing a moving block to move the second electric push rod and the cleaning block, thereby facilitating the cleaning of dust adhering to the side of the packaging box to be printed.

[0004] However, the above-mentioned device still has the following problems during implementation:

[0005] To make the packaging box surface more attractive and distinctive, printing equipment is used to print patterns on the surface of the packaging box. However, existing printing equipment requires a long time for the ink to solidify after printing on the packaging box. During this process, ink smudging is prone to occur, which in turn affects the printing effect. Utility Model Content

[0006] The purpose of this invention is to provide a packaging box printing apparatus to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A packaging box printing device includes a printing machine body, a drying box fixedly connected to the top of the printing machine body, a plurality of electric heating wires fixedly installed inside the drying box, a fan installed inside the drying box, an exhaust box fixedly installed on one side of the drying box, two connecting pipes fixedly connected to one side of the exhaust box, one end of the connecting pipes fixedly connected to one side of the drying box, and an exhaust pipe fixedly connected to the bottom of the exhaust box.

[0009] A transmission mechanism is fixedly mounted on the drying oven and can control the fan to reciprocate.

[0010] An exhaust mechanism is fixedly mounted on a transmission mechanism. When the transmission mechanism is running, the exhaust mechanism accelerates the discharge of water vapor.

[0011] Preferably, the transmission mechanism includes a motor fixedly installed on one side of the drying chamber, the output end of the motor extending into the interior of the drying chamber and fixedly connected to a lead screw, a moving block being drivenly connected to the surface of the lead screw, the bottom of the moving block being fixedly connected to the top of the fan, and one end of the lead screw extending into one side of the drying chamber and fixedly connected to a transmission disc.

[0012] Preferably, the exhaust mechanism includes a transmission rod fixedly connected to one side of the transmission disc, a push block is provided inside the exhaust box, a push rod is fixedly connected to the top of the push block, the top of the push rod extends through to the top of the exhaust box and is fixedly connected to the transmission block, and a transmission groove is provided on one side of the transmission block to cooperate with the transmission rod.

[0013] Preferably, a first one-way valve is fixedly installed on the surface of the connecting pipe, and a second one-way valve is fixedly installed on the surface of the exhaust pipe.

[0014] Preferably, a piston plate is fixedly connected to the bottom of the push block, and the piston plate is made of rubber.

[0015] Preferably, a sliding block is fixedly connected to the top of the moving block, and a sliding groove is provided on the inner wall of the drying oven to cooperate with the sliding block.

[0016] Preferably, a bearing is fitted on the surface of the lead screw, and one side of the transmission disc is rotatably connected to one side of the drying chamber via the bearing.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model, by setting a transmission mechanism, enables the packaging box to be conveyed to the drying chamber after printing by the printing press body. At the same time, the electric heating wire is activated to heat the inside of the drying chamber, and the fan is activated to blow hot air onto the surface of the packaging box. Simultaneously, the motor is activated to drive the lead screw to rotate. As the lead screw rotates, it drives the moving block to move back and forth. The fan moves back and forth synchronously with the moving block, so that the hot air is blown evenly onto the packaging box, thereby accelerating the ink solidification speed and improving the printing effect.

[0019] 2. This utility model, by setting up an exhaust mechanism, enables the transmission disc to rotate around the bearing while the lead screw rotates. The transmission rod rotates synchronously with the transmission disc. As the transmission rod rotates, its surface presses against the inner wall of the transmission groove, causing the transmission block to move up and down reciprocally. When the transmission block moves upward, it moves the push rod, push block, and piston plate upward. At this time, the exhaust box is under negative pressure, and the water vapor at the top of the drying box enters the exhaust box through the connecting pipe. When the transmission block moves downward, it drives the push rod, push block, and piston plate downward. The water vapor is compressed and discharged from the exhaust pipe. This cycle is repeated, which speeds up the discharge of water vapor from the drying box and prevents water vapor from condensing and dripping onto the surface of the packaging box.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 - Figure 6 The present invention provides the following technical solution:

[0029] Example 1:

[0030] The packaging box printing device includes a printing machine body 1, a drying box 2 fixedly connected to the top of the printing machine body 1, several electric heating wires 3 fixedly installed inside the drying box 2, a fan 4 installed inside the drying box 2, an exhaust box 5 fixedly installed on one side of the drying box 2, two connecting pipes 6 fixedly connected to one side of the exhaust box 5, one end of the connecting pipes 6 fixedly connected to one side of the drying box 2, and an exhaust pipe 7 fixedly connected to the bottom of the exhaust box 5.

[0031] The transmission mechanism is fixedly installed on the drying box 2 and can control the fan 4 to move back and forth.

[0032] The exhaust mechanism is fixedly mounted on the transmission mechanism. When the transmission mechanism is running, the exhaust mechanism will accelerate the discharge of water vapor.

[0033] The transmission mechanism includes a motor 8 fixedly installed on one side of the drying chamber 2. The output end of the motor 8 extends into the interior of the drying chamber 2 and is fixedly connected to a lead screw 9. A moving block 10 is connected to the surface of the lead screw 9. The bottom of the moving block 10 is fixedly connected to the top of the fan 4. One end of the lead screw 9 extends into one side of the drying chamber 2 and is fixedly connected to a transmission disc 11.

[0034] In this embodiment, considering that existing printing devices require a long time for ink to solidify after printing on packaging boxes, ink smudging is prone to occur during this process, thus affecting the printing effect, a transmission mechanism is set up so that after the packaging box is printed by the printing machine body 1, it is conveyed into the drying chamber 2. At the same time, the electric heating wire 3 is activated to heat the inside of the drying chamber 2, and the fan 4 is activated to blow hot air onto the surface of the packaging box. Simultaneously, the motor 8 is activated to drive the lead screw 9 to rotate. As the lead screw 9 rotates, it drives the moving block 10 to move back and forth. The fan 4 moves back and forth synchronously with the moving block 10, so that hot air is blown evenly onto the packaging box, thereby accelerating the ink solidification speed and improving the printing effect.

[0035] A sliding block 20 is fixedly connected to the top of the moving block 10, and a sliding groove 21 that cooperates with the sliding block 20 is provided on the inner wall of the drying box 2.

[0036] In this embodiment, by setting a sliding block 20 and a sliding groove 21, when the lead screw 9 rotates to transmit power to the moving block 10, the moving block 10 can only move back and forth along the trajectory of the sliding groove 21 under the restriction of the sliding block 20, which plays the role of restricting the movement trajectory.

[0037] A bearing 22 is fitted on the surface of the lead screw 9, and one side of the transmission disc 11 is rotatably connected to one side of the drying box 2 through the bearing 22.

[0038] In this embodiment, by setting the bearing 22, the transmission disk 11 and the lead screw 9 can be supported, while restricting them to rotate only around the bearing 22, thereby improving their stability during rotation.

[0039] Example 2:

[0040] Based on Embodiment 1, in this embodiment, the transmission mechanism controls the fan 4 to reciprocate and blow hot air evenly onto the packaging box, thereby increasing the ink solidification rate and thus improving the printing effect. However, considering that ink solidification will generate water vapor in the drying box 2, if it is not discharged in time, it will condense into water droplets and drip onto the packaging box, thus affecting the printing effect, the exhaust mechanism in this application includes a transmission rod 12 fixedly connected to one side of the transmission disk 11. A push block 13 is provided inside the exhaust box 5. A push rod 14 is fixedly connected to the top of the push block 13. The top of the push rod 14 extends through to the top of the exhaust box 5 and is fixedly connected to a transmission block 15. A transmission groove 16 is provided on one side of the transmission block 15 to cooperate with the transmission rod 12.

[0041] In this embodiment, by setting an exhaust mechanism, the transmission disc 11 can rotate around the bearing 22 while the lead screw 9 rotates, and the transmission rod 12 will rotate synchronously with the transmission disc 11. Figure 4 As shown, when the transmission rod 12 rotates, its surface will press against the inner wall of the transmission groove 16, causing the transmission block 15 to move up and down repeatedly. When the transmission block 15 moves upward, it will drive the push rod 14, the push block 13 and the piston plate 19 to move upward. At this time, the exhaust box 5 is under negative pressure, and the water vapor at the top of the drying box 2 will enter the exhaust box 5 through the connecting pipe 6. When the transmission block 15 moves downward, it will drive the push rod 14, the push block 13 and the piston plate 19 to move downward. The water vapor will be squeezed and discharged from the exhaust pipe 7. This cycle is repeated to speed up the discharge of water vapor in the drying box 2 and prevent water vapor from condensing and dripping on the surface of the packaging box.

[0042] It should be noted that S1 is the movement trajectory of the transmission rod 12, and S2 is the movement trajectory of the transmission block 15.

[0043] A first check valve 17 is fixedly installed on the surface of the connecting pipe 6, and a second check valve 18 is fixedly installed on the surface of the exhaust pipe 7.

[0044] In this embodiment, a first one-way valve 17 and a second one-way valve 18 are provided. The first one-way valve 17 is a valve that can only allow air to enter into the exhaust box 5, and the second one-way valve 18 is a valve that can only allow air to exit from the exhaust box 5. Therefore, when there is a negative pressure in the exhaust box 5, the gas will enter through the connecting pipe 6, and when the gas in the exhaust box 5 is compressed, the gas will be discharged through the exhaust pipe 7.

[0045] A piston plate 19 is fixedly connected to the bottom of the push block 13. The piston plate 19 is made of rubber.

[0046] In this embodiment, by setting the piston plate 19, the sealing performance of the exhaust box 5 can be improved. When the push block 13 moves up and down, the exhaust box 5 can be controlled to complete the process of intake and exhaust.

[0047] Working principle: After the packaging box is printed by the printing machine body 1, it will be conveyed into the drying chamber 2. At the same time, the electric heating wire 3 will be activated to heat the inside of the drying chamber 2. Simultaneously, the fan 4 will be activated to blow hot air onto the surface of the packaging box. At the same time, the motor 8 will be activated to drive the lead screw 9 to rotate. As the lead screw 9 rotates, it will drive the moving block 10 to move back and forth. The fan 4 will move the moving block 10 back and forth in sync, so that the hot air is blown evenly onto the packaging box, thereby accelerating the ink solidification speed and improving the printing effect.

[0048] As the lead screw 9 rotates, it causes the transmission disc 11 to rotate around the bearing 22, and the transmission rod 12 rotates synchronously with the transmission disc 11. Figure 4 As shown, when the transmission rod 12 rotates, its surface will press against the inner wall of the transmission groove 16, causing the transmission block 15 to move up and down reciprocally. When the transmission block 15 moves upward, it will drive the push rod 14, the push block 13 and the piston plate 19 to move upward. At this time, the exhaust box 5 is under negative pressure, and the water vapor at the top of the drying box 2 will enter the exhaust box 5 through the connecting pipe 6. When the transmission block 15 moves downward, it will drive the push rod 14, the push block 13 and the piston plate 19 to move downward. The water vapor will be squeezed and discharged from the exhaust pipe 7. This cycle is repeated, which speeds up the discharge of water vapor in the drying box 2 and prevents water vapor from condensing and dripping on the surface of the packaging box.

[0049] It should be noted that the printing press body 1, the electric heating wire 3, the fan 4 and the motor 8 are existing devices or equipment, or devices or equipment that can be implemented by existing technology. Furthermore, the specific composition and principle of the power supply of the printing press body 1, the electric heating wire 3, the fan 4 and the motor 8 are clear to those skilled in the art, and therefore will not be described in detail.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
